Practice Questions

Test your understanding with targeted questions

Question 1 Easy

Which type of cell is generally smaller and simpler: prokaryotic or eukaryotic?

  • Answer: Prokaryotic cells.
  • Hint: Think "Pro = No" (no nucleus or complex organelles).

💡 Hint: Think "Pro = No" (no nucleus or complex organelles).

Question 2 Easy

True or False: Both prokaryotic and eukaryotic cells contain DNA, ribosomes, and a cell membrane.

  • Answer: True.
  • Hint: These are basic requirements for all cells to function and reproduce.

Question 1

Which of these organisms is a prokaryote?

  • Type: mcq
  • Options: A) Mushroom, B) E. coli bacteria, C) Yeast, D) Oak Tree
  • Correct Answer: B
  • Explanation: Bacteria and Archaea are the only two domains that are prokaryotic.
  • Hint: Look for the simplest single-celled life form on the list.

💡 Hint: Look for the simplest single-celled life form on the list.

Question 2

True or False: Prokaryotic cells contain mitochondria to produce their energy.

  • Type: boolean
  • Options: True, False
  • Correct Answer: False
  • Explanation: Prokaryotes lack all membrane-bound organelles, including mitochondria. They perform energy reactions directly in their cytoplasm or across their cell membrane.
  • Hint: "Pro = No" membrane-bound organelles.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Microscope Mystery: You are observing a sample from a pond. You see a cell that is roughly long. It has a flagellum (a tail for swimming) but you cannot see a defined nucleus even with high-quality staining. Is this more likely a prokaryote or a eukaryote?

  • Solution: It is most likely a prokaryote. Its small size ( is at the top range for prokaryotes) and the absence of a nucleus are the key indicators. Many bacteria use flagella for movement.
  • Hint: Size and the "No Nucleus" rule are your best guides.

💡 Hint: Size and the "No Nucleus" rule are your best guides.

Challenge 2 Hard

Evolutionary Logic: Why would having membrane-bound organelles be an advantage for a cell?

  • Solution: It allows for compartmentalization. The cell can perform chemical reactions that require different environments (like different pH levels) at the same time without them interfering with each other. This makes the cell much more efficient at processing energy and waste.
  • Hint: Imagine trying to cook dinner, do laundry, and take a shower all in the same bucket versus having separate rooms.
